Knee Pain
Chronic knee pain is a major cause of lifestyle limitations and disabilities in adults that account for a significant number of doctor visits per year. Knee pain is reported in over half of adults over the age of 50. It is a strong predictor of future disability, and early treatment is likely to have a major influence on healthy aging. It has increased over time, and it has doubled in prevalence in the past 50 years, despite advances in patient care.
